While we sipped coffee, a neighbor joined us casually. 'Funny how well your MIL knows the house,' she remarked, her tone friendly. I chuckled, thinking of MIL’s fondness for her old home. 'She’s familiar with every nook and cranny,' the neighbor added, a hint of admiration in her voice. Something about the comment caught my attention. I laughed lightly, yet felt an unexpected curiosity about my MIL’s knowledge of our house.
